Planning EV Race Car

Hi All,
My name is Alex. I'm a big EV enthusiast and I have decided that I want to build a race car. I have little experience disassembling and reassembling cars but I am fairly apt with my hands and I'm fairly bright.
Here's a little bit about me, I am a student at a small university in upstate NY. I worked for two years for the University of Toronto on the original Surface and Google Glass with regards to notifications. I am going to major in Physics.

I have considered which car will serve as the basis for my car. I would prefer if I kept that private for now. Its a small car, perfect for racing.

The range I would like to achieve is around 80 miles at very high speed.

Parts:
Yasa 750 (H if available) x4 probably.

Battery pack ideas? Looking for Li-Ion

Rimac Battery Packs - if they are for sale.
Drive inverter?
Reinhart Controllers - PM250


Basic knowledge of EVs:

Energy goes in to the car from the grid through an adapter into a charger. The charger fills the pack. When you push down on the accelerator the controller allows current to flow into the inverter which converts the DC -> AC to spin a brushless motor. The motor usually connected to a reduction gear or gearbox spins the gears etc.

Is that correct? How does one program regenerative breaking?


That is really all that I have thought about.
I'm willing to push the limits financially right now. I would, however, like to keep track of the price of the parts.

Any and all help is greatly appreciated.

Best,
Alex
